Umpf... that's a bug in /usr/openwin/bin/resize which doesn't like the "sun" terminal type. I've fixed the problem by replacing "resize" with "tput cols ; tput lines" and fixed another reported problem where any of the demos failed when LC_NUMERIC or LC_ALL pointed to a locale with a radix point representation other than '.' (e.g. de_DE.UTF-8 uses ',' etc.). I've attched a new version as "termclock.ksh.2007-09-11.txt" - please test whether the problems are gone... ---- Bye, Roland P.S.: Alan: Who owns /usr/openwin/bin/resize these days ? -- __ . . __ (o.\ \/ /.o) roland.mainz at nrubsig.org \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 7950090 (;O/ \/ \O;) -------------- next part -------------- #!/bin/ksh93 # # CDDL HEADER START # # The contents of this file are subject to the terms of the # Common Development and Distribution License (the "License"). # You may not use this file except in compliance with the License. # # You can obtain a copy of the license at usr/src/OPENSOLARIS.LICENSE # or http://www.opensolaris.org/os/licensing. # See the License for the specific language governing permissions # and limitations under the License. # # When distributing Covered Code, include this CDDL HEADER in each # file and include the License file at usr/src/OPENSOLARIS.LICENSE. # If applicable, add the following below this CDDL HEADER, with the # fields enclosed by brackets "[]" replaced with your own identifying # information: Portions Copyright [yyyy] [name of copyright owner] # # CDDL HEADER END # # # Copyright 2007 Sun Microsystems, Inc.
